The 5K run/walk will take place on May 31 at 10 a.m. through the streets of downtown Grand Rapids, according to a Wednesday release.

Nana’s Run will raise funds for awareness and research of Amyotrophic Lateral Sclerosis. The run will benefit the ALS clinic at Mercy Health’s Hauenstein Neuroscience Center and the ALS Association Michigan Chapter.

It will pay tribute to Char VanderLaan, the grandmother to Cassie and Sydney DeVos, who died recently of ALS.

“Nana’s Run allows our family to focus our energy to create an event that will raise funds to benefit the continued efforts of ALS here in Grand Rapids at the Mercy Health Hauenstein Neuroscience Center,” Sydney DeVos said in a statement.

ALS, also known as Lou Gehrig’s disease, is a progressive neurodegenerative illness that affects nerve cells in the brain and spinal cord and is difficult to diagnose due to a lack of research, according to the release from Nana’s Run organizers.

The entry fee for the 5K is $25 if paid on or before May 28 and $30 beginning on May 29 through race day. Only cash and check will be accepted for race-day registration.
